Shooting Manual: Spot Metering

Posted on by

In some situations, traditional matrix metering will give you great results. Matrix metering tends to be the default mode for most cameras. As long as your scene is evenly lit, it will work great.

So you’ve tried and tried taking pictures outside when the lighting is best, but you still are missing the shots. The answer is your exposure. This is a tool you will need to learn how to use. I have a ways to go, but I’m very intrigued by it and want to learn how to take amazing photographs like the pros do in not-so-good light situations. Cameras are amazing little tools. When you really look at it though, it is just a light-proof box with a lens and light-sensitive digital card or film. The light enters the lens (aperture) and … Continue reading →

Study Finds Increased Diagnosis of ADHD

A study that was done in Southern California found that there has been an increase of the diagnoses of ADHD in the past ten years. This study included children who lived in Southern California. It is possible that the increase is due to a better understanding of the effects of prenatal exposure to certain substances. How many times have you heard of a study that says that the cases of ADHD are on the rise? Personally, I can think of quite a few of these types of studies that have made the news in the past couple of years. It … Continue reading →
